Toilet Flange Availability with 4 inch Diameter Hole

Updated 05/18/2020 | Published 07/02/2018

Question:

I am having trouble locating a toilet flange for a 2001 Holiday Rambler Ambassador. Its a screw in, but it is longer than most. Id say at least 4 inches in length. Do you have one?

We have the Replacement RV Toilet Floor Flange # T05-0784 which has a 4 inch diameter hole and .541 inches of usable female threads. But if you need something 4 inches long where the threads are we do not have anything.

Will this flange fit Thetford Aqua Magic Residential model # 42169? Thanks

I wish I could say for sure, but I wasn't able to track down the exact size/type flange that the Aqua Magic model you referenced uses. You'll just want to compare the thread and measurements of your existing flange to the dimensions on the Flange # T05-0784 product page to ensure compatibility.

@ChrisR The reason I am asking is that I do not have an existing flange to compare to. I am installing the toilet in a new cabin I am building. The toilet does not come with a flange and documentation does not refer to anything to with a flange

@DennisH I see - thanks for the clarification. I really wish I could find this info out, but without actually testing it or knowing detailed specs of the Aqua Magic model, there's just not a way for me to verify fitment. Dimensions for the flange are relatively standard, but the variable may be the type of thread you need - this particular unit has a FPT (female pipe thread). You might even try to reach out to Aqua Magic directly to see if they can provide you with any fit information.
